Question 1

How do I add drag-and-drop external events in svelte-fullcalendar?

Accepted Answer

You need to install the @fullcalendar/interaction plugin and use the included Draggable component, as shown in the README example. This allows dragging items into the calendar, with event data configured via the eventData prop.

Question 2

Is svelte-fullcalendar compatible with FullCalendar Scheduler for resource views?

Accepted Answer

Yes, it supports Scheduler's premium plugins like resource-timeline, but you must provide a schedulerLicense key. The README includes a code snippet demonstrating this integration with timeline views.

Question 3

What's the difference between svelte-fullcalendar and using FullCalendar directly in Svelte?

Accepted Answer

svelte-fullcalendar simplifies integration by handling reactive updates and component lifecycle, whereas vanilla FullCalendar requires manual DOM manipulation. However, the wrapper adds dependency layers and may lag behind FullCalendar updates.

Question 4

How to update calendar options dynamically, like changing the date view?

Accepted Answer

Use Svelte's reactivity by reassigning the options object; for direct control, access the Calendar API via ref with getApi() to call methods like next(). The README shows both approaches for modifying weekends and navigation.

Question 5

Does svelte-fullcalendar work with SvelteKit for server-side rendering?

Accepted Answer

It has limitations because FullCalendar's SSR support is incomplete upstream. You can fetch event data server-side, but the calendar UI itself may not render fully on the server, affecting SEO and load times.

Question 6

What are the performance costs of using this wrapper?

Accepted Answer

It adds bundle size from FullCalendar and its plugins, and reactive updates can cause re-renders. For large event sets, consider optimizing with virtual scrolling or lazy loading, though these depend on FullCalendar's underlying performance.

Question 7

Is there a free alternative to svelte-fullcalendar for basic calendars in Svelte?

Accepted Answer

Yes, lighter libraries like svelte-calendar or custom solutions might suffice for simple date pickers, but they lack FullCalendar's extensive features like drag-and-drop, scheduler views, and plugin ecosystem.
